IMEDEA-OTO includes more than 300 lots of Actinopterygian fish otoliths, with a total of approximately 43,000 samples, from the Mediterranean Institute for Advanced Studies (CSIC-UIB) thanks to the different campaigns led by Dr. Beatriz Morales-Nin. The samples come mainly from the Mediterranean Sea, the Antarctic Ocean and the Atlantic Ocean. There are representations of 157 species and 52 different families. The most represented orders are Perciformes, Gadiformes, Scorpaeniformes, Salmoniformes, respectively. The otoliths are whole or in dry preservation. The collection continues to grow.
Determination of the age and population parameters of osteitian fish. Microcomposition of calcified tissues as physiological indicators and of the water masses in which individuals have lived. Larval biology studies. Validation of the periodicity of growth structures.
Wide coverage of biotopes, from the coastal to the abyssal. Time series of otoliths of eppelagic and demersal commercial species. Otoliths from extreme habitats such as the deep ocean and Antarctic waters. Coverage for some species from larval to adult stage. Otoliths of coastal species marked with calcium chelators.
The samples come basically from the Mediterranean Sea, the Antarctic Ocean and the Atlantic Ocean.
